tifiliillis PATENT @iiiihitjiih CAR-TRUCK.

le it known that i, li'ittiiin l. ln'rricN- l noni, a citizen ol the United States, and a resident fir-ott and State oi iowa, liaye invented certain new and Truclis, oll which the following is a tull, clear, and exact lescriptionlleretolore ear-trucks, particularly ior freight-rais, have been made so that when assembling the parts thereof or when taking the same lo pieces bolts` and rivets had to be taken into account and inserted in the holes previously made for their reception and tightened or loosenedl and removed therel'rom. The use oi holts and rivets not only increases the cost et the truckboth as regarnis material and labor, but constitutes an element oi' weakness, because their use reduires the making et' holes and openings at points where the parts come in Contact and connected.

My invention designed to build a truck complete, the parts oi which are readily interloeked when being assembled, are securely and rigidly held. in interlocled relation when in use, and can be easily separated and knocked down for repair or substitution ot new parte or otherwise. rlliis .i aecomolisli by the means hereinafter i'uliy de scribed, and as particularly pointed out in the claims.

In the drawings, A A represent side iranies which are preferably, together with the ournal-boxes el, e at each end thereof, cast in one piece ot' metal and are with one exception constructed in other respects substantially similar to the side trames for car-trucks'iior which Letters Fatent oithe United States were granted to me October 6, i903, and numbered 740,617. The exception alluded to consists in providing the laterally-hanged sill ol the bolster-openingl of the side frames with a longitudinal groove c in its upper surface, preferably in the saine plane as the web of the side iranies.- Connecting these side i'ranies is a spriiig-planlr B, the ends oi which rest upon the sill et the bolster-opei'iing in the saine and are interloclied therewith by having a transverse projeeton or tenen d on its under side near each end, which are of such dimensions and are so located that when the plank B is in proper position they will enter groovesc. The ends ot' said ilank, preferably that portion resting upon the sills of the bolster-openings oi' the side iranies, are .provided with a series oi`l upwardlyrojeeting bosses a e, that are located in nient with the axis of the bolster-springs C C. These bolster-springs 'C are confined hetween an upper and lower spring-seat .D i), each oi which consists of a suitable plate having centering bosses f f, made by depressing the n'ietal on the sides of the plates opposite the springs, so as to provide eoncavities that will no matter which end et the springs is lowermest i it over the bosses e e. oi the spring` plank, and thereby be prevented from being displaced in a horizontal direction.l

"lie central portion el' the spring-seats D are provided with bosses g, that project from each seat. toward the opposite one to an extent greater than the bosses e and are iliade by depressies@r the opposite side of the seats. 'lfhese springs are before being placed under the bolster' compressed to an extent sufficient to enable them to sustain the weight oi' roo the car-body without depression, "and the spring-seats are secured together to retain said springs in such compressed condition by a bolt il). The ends otthis/bolt extend through suitable openings in the centers of the bosses g ol the springseats and are headed, and when under the greater weight of the load carried by the car the springs are compressed the headed ends eii the bolt have longitudinal play in the coneavty of the said 1 io jected.

The lower portion of the bosses g, Whose depth i's sufficient to accommodate any play of the bolt under any compression lto which the springs may be sub- The ends of the bolster F extend through the bolster-openings ofthe side frames A and rest upon and are supported by the springs C. rlhe .vertical and transverse dimensions of the ends of the bolster are such that they can enter and normally occupy 'the Vupper portion of the bolster-openings of the side frames, and said ends are provided with guide-blocks 't i, suitably secured to the sides of the same in the usual manner, that engage the upper portion of the guide-columns j, forming the sides of the bolster-opening. guide-columns are recessed in the edges next the bolster-openings to form-insets 7c 7f, vrhich makes the lower portion of said openings wider, so that u on the springs being removed from under tlib ends of the bolster and said bolster lowered until about in the position shown in the right-hand half of Fig. 4 of the drawings said 25 bolster can be shifted longitudinally and removed.` In orderto permit of the removal ofthe springs, the height of the bolster-opening must be such that with. the bolster in. proper position there will be under ordinary conditions sufficient space between the top of the ends of the bolster and the upper arch of. the side frame to permit the bolster to be raised off said springs and the latter removed from under the ends thereof.

After .the spring-plank, the bolster-springs,

v and the bolster' have been removed from the 'truck the side frames are lifted slightly, so as to permit'of the removal of the journal-bearings G from ofi the `journals of the axle H and.

out of the journal-boxes a, whereupon the' side frames, which beforewere keyed to the axle by said bearings G, can be removed.

Projecting inward from the upper arch of the side frames above the guide-columns are studs l l, and journaled upon these studs are links or hangers' J J, whose '"lower ends are attached to and `support the brake-shoe relation-Without bolts or rivets.

heads K, which, as shown, are secured to the ends of and are connected by the brake-beam L. In assembling the partsof my im roved truck the brake-shoe gear `is the last t "nglto be installed in lace; ybut when knocking down the truck itis jthe iirst thing to be removed. y
